Question: Over time, bacteria have become increasingly resistant to antibiotics. which of the following best explains this in terms of natural selection?
The best explanation for the increase of antibiotic resistance in bacteria in terms of natural selection is:
- Mutations and selection: Bacteria can acquire random mutations in their DNA that may confer resistance to certain antibiotics. When exposed to antibiotics, the resistant bacteria survive and reproduce, while the susceptible bacteria die. This process selects for the resistant bacteria, increasing their frequency in the population.
